It is well know that there are two kinds of materials, reinforcement and concrete, in the towering reinforced concrete chimney.
Strain rate of reinforcement and concrete was setted by the Cowper - Symonds model [10], namely (10) In Equation (10), is the yield stress of material, ε is the strain rate of materials, C and P are the strain rate parameters of Cowper- Symonds, is the initial stress which applied on the material, Ep is the plastic hardening modulus of material, is the effective plastic strain of material, β is the parameters of plastic kinematic hardening model.
Material is in the state of hardening model when β is zero.
And the materials at the blasting gap can get the function of failure criterion by modifying the K-file.
And the differences between the numerical simulation results and the actual results are the reason that there are deviations between the material parameters for numerical simulation and the actual mechanical properties of materials.

Gas sensors using NST film as sensitive material were presented in this paper too.
Extensive efforts have been put into integrating nanostructured materials into microelectronic devices, for instance, electronic noses.
